19GE5022R0069: Additional Information for Statement of Work

FLASHING DETAILING

A. Using a trowel, apply flashing grade cement at any areas where there are roof terminations, penetrations, flashings, seams or transitional joints. It may be applied to both horizontal and vertical surfaces and will bridge gaps up to 12mm in width.

B. Reinforcing fabric may be embedded in flashing cement for additional strength and mobility.

However based on the thickness and consistency of the material, the fabric may be difficult to embed and cause excessive wrinkles and gaps. Fabric must be used to bridge large openings.

C. Reinforce all inside and outside corners with a 100mm diameter conical piece of fabric prior to installing the flashing layer.

D. Flashing is typically constructed as a two-part assembly consisting of a vertical wrap and a horizontal target patch. There must be a minimum of a 100mm overlap between vertical and horizontal flashing components.

E. Flashing material shall extend 100mm minimum onto drains, scuppers, or insert flanges.

TOPCOAT APPLICATIONS

A. Coverage rate: Apply topcoats at 0.7–1.4 gallons (2.65-5.30L) per 100 square feet (9 SM).

Based on first topcoat smooth texture, the second topcoat may be reduced to 0.5 gallons (2.50L) to 100 square feet (9 SM).

B. Brush, roll or spray the elastomeric topcoat evenly onto the surface to fully saturate the primed surfaces in one application with brush or roller; multiple applications with sprayer. DO NOT allow coating to pond or collect in low areas.

C. Apply elastomeric topcoat up to the perimeter roof edge of the flashing terminations and penetrations.

D. Allow to cure for a minimum of twenty-four (24) hours before second finish coat.

E. DO NOT allow any excess coating to remain on the surface, the correct amount of coating will leave no fibrous surface texture from the fleece fabric. The final coating should be smooth, uniform, and bright white.

F. Dry finish (Primer + Base coat with fabric + 2 topcoats) thickness: 48 mils.

FIELD QUALITY CONTROL

The Embassy or OBO may direct Contractor to stop applying coatings if results show materials being used do not comply with specified requirements or coating materials and accessories are not compatible. Contractor shall remove noncomplying coating materials from site, pay for testing, and recoat surfaces.

After completing coating application, clean spattered surfaces. Remove spattered coatings by washing, scraping, or other methods. Do not scratch or damage adjacent finished surfaces.

Thoroughly mixed and cured coating products may be disposed of in standard landfills. Uncured products are considered a hazardous material and must be handled as such, and disposed in accordance with local regulations.

C. Reinstall all disconnected equipment after completion of coating works. Reset rooftop equipment on protective pads. Reconnect pipe, conduit, wiring, and reactivation of the equipment to its original condition shall be provided by Contractor D. Correct any damage by cleaning, repairing or replacing, and painting as acceptable to the Embassy.
